Ectopic pancreas associated with a choledochal cyst and extrahepatic biliary atresia

Two children with incidentally-diagnosed ectopic pancreatic tissue in the jejunum at surgery for extrahepatic biliary atresia (EHBA) and choledochal cyst (CC) are reported. No case has been reported in the literature describing the association of a CC with ectopic pancreas, and only one case of EHBA associated with ectopic pancreas has been reported. We believe that incidentally-detected ectopic pancreatic tissue should be excised, even though the patient is symptom-free, in order to prevent the risk of serious complications due to either the mass effect or the potential for acute pancreatitis, cystic degeneration, or malignant transformation at a later date.
